Question

我的项目中有以下结构：

+main_proj

    +modules
        +user_ops
            -add_user.py
            -remove_user.py
            -__init.py
    +common
        -user_operations.py
        -__init__.py
    -main.py
    -__init__.py

我的问题是add_user.py和remove_user.py都依赖于user_operations，当我尝试调用它们时，我收到relative import in non-package错误。

Main.py

from common import user_operations as user_operations  #This works ok

if __name__ == '__main__':

    command = "remove_user"

    #Load usage, functions and paths to modules
    __doc__, function_dictionary, modules = utilities.load_modules()

    #Get function from dictionary
    func = function_dictionary[command]

    #Execute function
    result = func(api_root, arguments, simulate, headers)

func(api_root, arguments, simulate, headers)

调用的模块

remove_user_front.py

from ...common import user_operations as user_operations

    def remove_user_front(api_root, arguments, simulate, headers):

        #Get users in this account
        users = user_operations.get_users(api_root, arguments["<source_account>"], headers)

        #This is smelly
        if arguments["--id"]:
            type = "id"
        elif arguments["--username"]:
            type = "username"
        #End smell

        result = remove_user(api_root, arguments["<source_account>"], arguments["<user_id>"], type, simulate, headers)

        if not result:
            return False
        else:
            return True

    function_dictionary = {"remove_user" : remove_user_front}

错误：

Traceback (most recent call last):
  File "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensio

    imported_module = imp.load_source('recovery',module)

remove_user_front.py", line 1, in <module>
    from ...common import user_operations as user_operations
ValueError: Attempted relative import in non-package

有人知道如何保留我的文件结构并启用modules下的模块来使用common下的模块吗？

Answer 1

当你的应用程序启动时，它会获得一个os.path。

尝试导入任何内容的每个模块都将具有相同的路径。这意味着你需要从user_ops导入一些东西的共同文件需要导入它，就好像它是你的main.py那样导入它们。

试

from modules.user_ops import add_user

你的user_operations中的

试图在非包装中进行相对导入
